Avenue 8 Overpass

Asphalt paving is now largely complete for the roadway leading up to the Avenue 8 overcrossing bridge, in preparation for the Madera County road’s reopening. Trucks filled with hot asphalt empty their loads into the front of a paving machine, which then lays out a slab of pavement about six-inches thick, as vibrating rollers compact it. Final pavement striping, drainage inlets, and guardrail installation are the last steps prior to reopening the road.

As at Avenue 11, the bridge deck for the Avenue 8 overcrossing in Madera County is mostly complete, but final paving for the approaches waits for better weather.

Utility conduit is also being installed for future utilities.
